Typical Heating System Issues

Heating units may encounter several problems over extended use. Here are some of the most common malfunctions I handle in my work:

Furnace Won’t Turn On – This might happen due to a faulty thermostat, tripped circuit breaker, or sensor failure.
Poor Heat Circulation – Blower motor problems can reduce efficiency.
Unusual Sounds – Clanking or grinding sounds often indicate a problem with the heat exchanger.
Frequent Cycling – This could be due to a dirty filter.
Gas Burner Won’t Stay Lit – A gas supply problem may stop the furnace from staying on.

Basic Furnace Maintenance Tips

Proactive maintenance is critical to prevent costly breakdowns. Here are a few essential maintenance recommendations:

Keep Air Filters Clean
A dirty air filter reduces airflow, leading to overheating. Replace the filter as recommended by the manufacturer.
Keep the Blower Fan in Good Condition
The fan pushes warm air into your living space. Dust buildup can reduce efficiency.
Test the Thermostat
A miscalibrated thermostat can lead to unbalanced temperatures. Monitor the temperature settings to verify the system is responding accurately.
Check for Cracks or Damage
A damaged heat exchanger can leak carbon monoxide—a potentially deadly gas. If you notice discoloration, schedule an inspection.
Maintain Unobstructed Airflow
Obstructed vents or flue pipes can cause dangerous backdrafts. Remove obstructions to maximize efficiency.
Book a Yearly Furnace Checkup
A yearly tune-up by a qualified HVAC technician reduces the risk of expensive issues. This covers testing safety controls.
